Abstract

The present invention relates to a microwave oven, and more particularly, to a device for cooling electric equipments of hooded microwave oven. The device comprises a ventilation motor assembly 40 mounted on the top of a cavity 20, for forming both a flow of air for a hood function and a flow of air for dissipating heat from the electric equipments; and a suction grill 50 through which outer air is sucked to the top of the cavity 20 by suction force of the ventilation motor assembly 40. The electric equipments are positioned in a flow of the air that is sucked through the suction grill 50 to the top of the cavity 20 and flows to the ventilation motor assembly 40. According to the present invention, since a flow of air for dissipating heat from the electric equipments is linearly formed, its cooling efficiency and the reliability of the electric equipments are enhanced.
